On Jul 23, we celebrated the 14th anniversary of Chandra's launch and
14 years of successful scientific operations. The spacecraft and
instruments continue to operate superbly well and we look forward with
excitement to the coming year of science discovery!

During the last week Chandra completed the observing schedule as
planned.

Real-time procedures were executed on Jul 20 to prepare for the first
eclipse of the summer 2013 season: one to activate SCS 29, one to dump
and clear the EPS glitch counters, and one to set the short eclipse
flag to "true". Chandra passed through the first and second eclipses
of the season on Jul 21 and 23 respectively, with nominal power and
thermal performance. A real-time procedure was executed on Jul 24 to
set the short eclipse flag to "false" in preparation for the
medium-length eclipses expected for the remainder of the season.

Of note last week was the successful transition to operations on
Jul 24 of an updated version of the Operations Control Center ground
system. The update replaces a system that has been in operation since
Nov 2005 and includes new network and computer hardware as well
as updated versions of the ground-system software. The new ground
system provides a more capable, more secure, more flexible, more
maintainable, and "greener" data system.
